IMPROVEMENT IN GROSS'BAR LOOK FOR DOORS, 6to.

To ALL WHoM 1r MAYeoNoERN:

Be it known that 1I, JAMES E. HANGER, of Staunton, in the county of Augusta, and State of' Virginia, have invented a new and improved Cross-Bar Lock; and I do hereby declare that the following is a full, clear, andexact description thereof, which will enable those skilled in the art to make and useithe same, reference being had to the'aecompanyingdrawingm forming part of this specification, inwhich- The gure represents my improved lock attached to a door, part of the outer plate being broken away, to show the construction. l

My invention hasfor its 'object to furnish an improved cross-bar lock, simple in construction, easily operated, and edective in operation, and it consists in the construction and combination of the parts by'whichthe cross-,bar is operated, as hereinafter more fully described.

A is the door, and l B arethe side-posts or casings.

C is a close keeper attached to one of the side-posts B, and

D is an open keeper attached to the other side-post. v

E is the cross-bar, which is pivoted between the outer plate, F, and tho `inner plate, G, ofvthe lock, inthe mannery hereinafter described.

IjI is a curved rack, which is made in substantially the form shown in the ligure, and which is rigidly attached to the cross-bar E. i

I is a pinion-wheel, pivoted between the plates F and G of the lock, in such a position that Vits teeth mayV mesh into the teeth ofthe curved rack I-Las shownin the drawing, so that'the pinion-wheel I may be revolved .by operatingthe cross-bar E, and so that the cross-bar E may be operated by revolving the pinion-wheel I.

' f J is a lever, the ends of which are turned up in opposite directions, or have pins formed upon them, one

Vof' which entersA a hole in the disk K, attached to or forming a part of the pinion-wheel I, and the other enters n hole inthe outer plate, F, in the bottom of the key-recess L. p The cross-bar E is guided in its movements by the pin M attached to said bar, and moving .through the slot N inthe outer plate, F, and by the pin 0,' which enters a straight slot in the frame of the curved rack II,

. asshown in the drawimgs.V

In operating the cross-bar Efromthe inneraide of the door, the key is insertedin the `key-hole, and brought into such a position that it may operate the lever J to release the pinion-wheel I, then,v by' taking hold of the cross-bar E, it maybe operated to unbarlthe door.

The iii-st movement of the cross-bar E is straight until its end is withdrawn from the close keepers C. It then swings around, freeing its other end from the open keeper D, and taking a position parallel with 'the length of the door, allowing the door to be opened. i

In operatingthe cross-bar E from the outer side of the-door, the key is inserted-in the key-hole and brought intosuch a position as to operate thelever J to free `the pinion-wbeel I. Then, by means of. the key, the said pinion-wheelmay be revolved, carrying the cross-bar E through the movements hereinbefore described, and unbnrring the door.

The door is barred or fastened in the' same manner us it is unbarred or unfastened, the movements of the various parts being reversed.

Ielaim as new, and desire to secure by Letters-Patent* v 1. The combination of the curved rack H, constructed substantially as herein shown and described, with the crosrvbar E and pinion-wheel I, `as und for the purpose set forth.

2. Giving to the cross-bar E a longitudinal and swinging movement, by means ofthe pin M projecting from the cross-bar, and working iii the curved slot N of the case F, fastened substantially as herein shown and described, and for .the purpose set forth.

JAMES HANGER. l
